When my girlfriends and I cruise together, we stay in the same cabin. We have only been allowed to use one certificate in the past. We all usually buy a certificate when we're on a ship that offers them. It just means we have to take turns using them and make sure we book enough cruises so they don't expire and everyone gets a turn.

Thanks! I've read some conflicting reports about this. I asked a friend to call the General Reservations number and they told her two people could use them in the same cabin. I originally thought that you could use two on one cabin, but they would only let one OBC be issued for the cabin. Regardless, they are a good deal and am going to get a few on my next cruise.

Posted below are the current rules for use. One of which I will expand on after;

Terms and Condition for the Certificate

1. Valid for new bookings only
2. Only one certificate will be applicable per stateroom
3. Not combinable with Friends & Family, Interline, Travel Agent Rate or restricted fares
4. Certificates Issued Prior to 1/04/11: Certificates must be redeemed within 48 months from date of issue; based on previous terms, there may be 60 month certificates still in circulation.
5. Certificates issued 1/07/11 and beyond: Certificates must be redeemed within 24 months from date of issue and guests must sail within 36 months from date of issue = book within 2 years/cruise within 3 years.
6. Applicable to Group bookings
7. Deposit is refundable however non-transferable

---------------------------------------------------

I have verified today that rule number 1. has some flexibility in that they can be used as long as the booking is outside of penalty and before final payment. I am also happy to report I was told the current processing time is 7 - 10 business days. This is a vast improvement over the backlog they had going on last year. Also they still must be sent by certified mail.

I hope the tax man is kind to me as I want to buy 2 on my next cruise.
